To all whom, it, may concern; j Be it known that-I, ERIC BROWN, a subject of the King of Great Britain, and a resident of Baden, Switzerland, have invented certain new and useful Improvements in Means for Coupling Steam-Turbines, of whi ch the following is a specification.

The subject of my invention is an improvement in the means of coupling steam-turbines, and is designed for use in those cases in which two or more separate steam-turbines, either each for itself or in con'unction, drive a common shaft in the same irection. The invention is therefore particularly applicable when steam-turbines are employed fo'r the propulsion of shi s.

According to t 's invention the rotary element of a steam-turbine is mounted on a hollow shaft through which there freely passes or in which there is mounted a solid shaft, and the problem, well known in the case of land steam-turbines .with separate adjacent shafts, of renderingthe rotaryelement of the oneturbine adjustable independent of that of the other by means ofalongitudinallymoving clutch is solved by the latter being located between the solid and the hollow shaft in such manner that art of the turbine mounted on the hollow s aft, which is dependent upon the clutch, is rendered adjustable in axial direction relatively to the remaining turbine parts, the clutch at the same time, owing to its longitudinal movement, admitting of such adjustability. By this arrangementthe possibility is presented of the rotary element and the blades connectedwith it, and likewise the packing parts, being adjusted in axial direction for the turbinein uestion independent of the adjustment in t e other turbines working on the same common shaft. The clutch is preferably one capable of disengagement, so that Athe hollow shaft, with its turbine, may be brought to rest when this turbine is not re uired to work.

My invention 1s illustrated diagrammat# ically in the accompanying drawings, yin which- Fi'gure 1 is a view showing a part of one turbine in elevation and another turbine in section with a single shaft common to the two turbines, Fig. 2 a detail view showing a por- 1 packing parts drawn to a longer sca e.

' In the drawings I have for convenience 11- dicatedbut two turbines, (numbered l and 2,) the first of these being shown in section and the second in elevation.

A is the hollow turbine-shaft, which receiges the solid shaft H, with guide-blocks B 2.

K is the clutch which cou les the shafts A H and whose engaging mem ers allow a relative axial motion.

S represents staying and adjusting bolts, which with the aid of the two-part corrugated bearing M, secured to the turbine-casing, enable the turbine rotary element T, mounted on the hollow shaft, with its blades V and the rings of the corrugated packingL, to be adjusted in axial direction relatively to the corresponding. parts on the stationary casing.

In order that the clutch may be o erated to disconnect the tubular shaft from t e solid shaft, it is only necessary to move it longitudinally away from the tubular element suficiently to disengage the interlocking parts, this movement being'permitted by the elongated slot of the clutch member (shown in dotted lines) with which the pin k on the shaft engages.

Having thus described my invention, what I claim is- 1. In combination,a plurality of steamturbines coaxially arranged and each comprising al stationary and a rotary element, a tubular shaft for each turbine by which the rotary 'element is carried, means whereby such tubular shaft and its rotary element may be adjusted longitudinally of the sta-fy tionary element, a single shaft commonftoall f the turbines and'extendinginto thetbiar shafts, and clutch mechanism intepo's'd;V between each tubular'shaft and the singleshat, substantially as described. f 2. In a steam-turbina, a stationary element, a rotary element within the same, a

tubular shaft upon which the rotary element is rigidly carried, means for adjusting the tubular shaft with its rotary elementlongitudinally with relation to the stationa element, a driving-shaft extending through t e tubular shaft, and clutch mechanism interposed be tween the tubular shaft and driving-shaft, substantially as described.

3. In a steam-turbine, a stationary element, a rotary element within the same, a tubular shaft upon which the rotaryelement is rigidly can'ied, means 'for adjusting the tuno IooA huhu' shaft witlits rotary 010111011t longitudinzLlly with 1'0l11ti011 to tl10 stationary 0l0111011t, a1 driving-shaft oxtmlding through th0 tubu- 1111 shaft, 11nd 111011115 for 00111100t111;r :1nd dscon1100ti11g thc tubular shaft :1nd drivingshaft 1r0sp0ct'1v0 of th0 :1dj11st111011t 0f th0 tubular shaft, substantially as described.
